摘要：

In order to increase the effectiveness of water splitting by TiO2 photocatalysts, the effects of the Pt deposition method and the Pt concentration on the hydrogen production rate of Pt-deposited TiO2 were studied. Among the methods used in this study, the formaidehyde method resulted in the highest rate of H-2 production. The amount of Pt on TiO2 had to be optimized to obtain the highest rate of H2 production. The Pt particles on the Pt-deposited TiO2 prepared by the present method were too small or too thin to be observed by transmission electron microscopy.
